# Build a game from a prompt

Describe a game and get a playable scene inside the real engine.

`summer_create_scene` `summer_add_node` `summer_set_prop` `summer_play` `summer_get_diagnostics`

Demo folgt in Kürze. Dieser Bereich zeigt eine Loop-Aufnahme, sobald das Content-Team sie aufgenommen hat.

So sieht es aus

A side-scroller where a fox collects fireflies at night.

Scaffolding the scene, adding the player and a firefly collectible, then testing it in Play mode.

summer\_create\_scene -> summer\_add\_node x6 -> summer\_play -> summer\_get\_diagnostics

It runs clean: the fox moves, collects fireflies, and the score updates.
